PORTLAND, Ore. -- The Portland Trail Blazers extended the contracts of forward Noah Vonleh and guard Shabazz Napier on Monday, keeping both players with the team through the 2017-18 season.

Vonleh, who turned 21 in August, averaged 3.6 points and 3.9 rebounds in 15.1 minutes per game last season with the Trail Blazers. He was acquired from Charlotte in June 2015 in the trade that sent Nicolas Batum to the Hornets.

Napier, 24, averaged 4.4 points and 2.1 assists in 15.2 minutes per game during the past two seasons with the Miami Heat and Orlando Magic. The Blazers traded for Napier in July.

Portland opens its season Tuesday against the Utah Jazz.

Both Vonleh and Napier are still on the contracts they signed as rookies prior to the 2014-15 NBA season. Under the terms of the NBA's collective bargaining agreement, the first two years of a rookie-scale contract are guaranteed. Teams then have the right to exercise options on both the third and fourth years of the contract.

The third-year option was picked up for both players last season. The deadline to exercise the fourth-year contract options for both players was Oct. 31.

Vonleh, who was drafted with the ninth overall selection in the 2014 NBA Draft, will make $3,505,233 in the fourth year of his rookie contract. He is making $2,751,360 this season.

Napier, who was selected with the 24th overall selection in the same draft, will make $2,361,360 next season. He will earn $1,350,120 this season.
